* getline.m4 (AM_FUNC_GETLINE): Don't bother checking for
string.h any more.
- * progtest.m4 (AM_PATH_PROG_WITH_TEST):
- Output "no" only if $1 isn't $4.
+ * progtest.m4 (AM_PATH_PROG_WITH_TEST): If not found, print "no",
+ not the default value.
- * mbswidth.m4 (jm_PREREQ_MBSWIDTH):
- No longer requires AM_C_PROTOTYPES.
- Check for iswcntrl, mbsinit. Use AC_TRY_COMPILE, not AC_CHECK_DECLS,
- for portability to Autoconf 2.13.

+ * mbswidth.m4 (jm_PREREQ_MBSWIDTH): Don't require AM_C_PROTOTYPES.
+ Also check for mbsinit. Needed for SCO 3.2v5.0.2.
+ Also include <string.h>; this is where AIX 3.2.5 declares wcwidth.
+ Also check for iswcntrl, used for wcwidth fallback.
+ Use AC_TRY_COMPILE to emulate AC_CHECK_DECLS, for portability
+ to Autoconf 2.13.
